Example 2

Initial viscosities of the adhesive formulations from Example 1 were measured, as described herein, at 23° C. using a Brookfield viscometer spindle number 6, at 20 rpm. Results of the initial viscosity measurements under these conditions are shown in Table 3 below.

Adhesive formulations 1 to 5 from Example 1 were then aged for 28 days at 50° C. to determine shelf life using the procedure described herein, infra. In the present specific non-limiting example, an adhesive formulation was determined to “pass” shelf life when a measured test viscosity of the adhesive formulation (i.e., after aging for 28 days at 50° C.) was within ±40% of the measured initial viscosity. An indication of whether each adhesive formulation passed the shelf life test described herein, is shown below in Table 3.

Example 3

Adhesive formulations 1 to 5 were applied in a sufficient amount to form a bond between an exemplary roofing membrane and an exemplary roof substrate. As described herein, the sufficient amount of the adhesive formulation applied to the roofing membrane was, in the present non-limiting example, expressed as a ratio of the amount of the adhesive formulation applied to the roofing membrane in gallons to the square footage of the roofing membrane.

The resulting exemplary roofing systems were tested for cure time and wind uplift resistance.

Cure time was measured, as described herein, at 23° C. and 50% relative humidity using a dry time recorder from Gardco®.

The exemplary roofing systems were aged for 28 days. Wind uplift resistance of the resulting aged exemplary roof systems was then evaluated using the 12×24 ft Wind Uplift Test described herein, infra, at 23° C. and 50% relative humidity.

As described herein, infra, in the present example, an exemplary roofing membrane that is designated as “untreated” was not subjected to plasma treatment, whereas a “treated” roofing membrane was subjected to plasma treatment before application of the adhesive formulation and bonding of the adhesive formulation to the roof substrate.

In the present non-limiting example, the tested roofing membranes were thermoplastic polyolefin (TPO) roofing membranes.

Results are shown below in Table 4.

As described herein, the sufficient amount of the adhesive formulation applied to the roofing membrane was, in the present non-limiting example, expressed as a ratio of the amount of the adhesive formulation applied to the roofing membrane in gallons to the square footage of the roofing membrane.

In the present non-limiting example, the exemplary roof substrate was a polyisocyanurate (ISO) foam board. In the present non-limiting example, the exemplary roofing membrane was a polyvinyl chloride (PVC) roofing membrane. In particular, two specific samples of the PVC roofing membrane were tested—a sample PVC membrane with a liquid plasticizer (PVC-LP) and a sample PVC membrane with a ketone ethylene ester plasticizer (PVC-KEE).

Cure time and wind uplift were evaluated using the same procedure and under the same conditions (such as but not limited to temperature, relative humidity, and aging time) as Example 3 and Comparative Example 3.

Results are shown below in Table 6.
